> ELI5: quantum physics things get REALLY weird when you zoom in super tiny imagine zooming in on a marble… past atoms… until things stop making sense Marble normal world zoom in Atom tiny building block zoom MORE ? ? ? Quantum World rules break here 🤯 ⚡ HERE BE WEIRDNESS ⚡ so weird… Why does it matter? ✦ Powers your phone's chips & lasers ✦ Explains why the sun shines ✦ Future: quantum computers! 3 big ideas in quantum physics — explained with simple things you know ① SUPERPOSITION 😀 HEADS OR 🌀 TAILS 🌀 BOTH at once! (while spinning) A quantum particle is like a spinning coin — heads AND tails until you look at it (it lands) ② WAVE-PARTICLE acts like a WAVE (spreads out) ↕ acts like a BALL (hits one spot) Like a pebble in water — it makes waves, but when it hits, it's just one tiny point electrons do BOTH 🤯 ③ ENTANGLEMENT 🧤 box A 📍 Earth 🧤 box B 🚀 Mars linked! 👈 open it: LEFT ⚡ instantly! 👉 must be: RIGHT Two particles linked forever — check one glove on Earth, instantly know the other on Mars Einstein called it "spooky action" eli5.cc

// eli5Quantum physics is like studying the tiniest toys in the world—so tiny you can't see them! [1] These super tiny things (called particles) act really weird and different from the big things around us. Imagine a toy that can be in two places at the same time, or a spinning top that spins both ways at once until you look at it. [3] That's kind of how quantum physics works—things act strange and unpredictable at the tiniest scales. [2]
